Below is a focused comparison of Romanian / Romania‑sold sleepwear brands and product types for winter warmth, with practical buying tips. I emphasize materials and construction (the main drivers of warmth) and cite sources for the most important brand/fabric claims.

Short summary (quick picks)

• Maximum cosy warmth (budget): fleece/polar or brushed polyester sets from mass retailers (examples sold under Tex/house brands). (Carrefour.ro)
• Warm + natural-feel (good balance): cotton flannel sets or heavy brushed cotton from Romanian brands such as Sofiaman and Ama Pijama. (thetrends.ro)
• Lightweight luxury (less insulating in deep cold): silk sleepwear (Megami — handmade silk) — elegant but not the warmest choice for freezing nights. (businessmagazin.ro)
• Thermal/technical options for kids: thermal/“termal” pajama sets (Penti carries thermal kids sets in Romania). (Penti.com.ro)

Detailed comparison (what affects winter warmth)

1. Fabrics and warmth (how to read labels)

• Fleece / polar / 100% polyester (brushed): very warm, traps air, lightweight — best for staying very warm at home. Often sold by mass/retail labels (Tex at Carrefour) and in novelty onesies. (Carrefour.ro)
• Brushed cotton / cotton flannel: warm, breathable, comfy for most indoor winters. Sofiaman and other Romanian pajama makers use cotton flannel for winter collections. (thetrends.ro)
• Thermal knit blends (polyester + elastane or cotton blends): designed to hold body heat while fitting close to the body — good underlayers or as pajamas when active (Penti sells thermal kids’ sets). (Penti.com.ro)
• Silk (natural silk): cozy to the touch and thermoregulatory but thin — keeps you comfortable in mildly cool conditions, not ideal as sole insulation in very cold rooms. Megami (Romanian maker) produces silk sleepwear. (businessmagazin.ro)

2. Brands sold in Romania (notes about origin and positioning)

• Sofiaman: Romanian brand with seasonal winter pajama lines (coordinated family sets, flannel/cotton options) — mid‑range, focuses on festive/winter collections. Good balance of style + cotton flannel warmth. (thetrends.ro)
• Ama Pijama: Romanian-made pajamas (manufactured in Romania) — range includes women’s and children’s sets; traditional sewing/manufacturing focus suggests availability of heavier cotton pieces. (businessmagazin.ro)
• Megami: artisan brand known for handmade silk sleepwear — luxury/niche, not focused on heavyweight insulation. (businessmagazin.ro)
• Retail/house brands (Tex at Carrefour, Penti in Romania): carry very warm fleece/thermal and budget options; widely available and often the warmest by fabric choice (polar/fleece, thermal knits). Tex (Carrefour) lists 100% polyester polar pajamas for winter. Penti lists thermal kids’ sets. (Carrefour.ro)

3. Construction & fit — why it matters

• Close‑fit thermal knits trap a warm layer of air against the skin and work well under blankets. (Penti’s “termal” labeled sets use this approach). (Penti.com.ro)
• Loose flannel/cotton is comfortable and insulating when layered; thicker flannel is a good middle ground (Sofiaman seasonal lines often use heavier cotton/flannel). (thetrends.ro)
• Onesies / union suits (fleece or plush): full coverage (hood, cuffs, footed) gives excellent warmth for sedentary evenings. Many retailers in Romania sell plush salopettes/onesies. (eurostoc.ro)

4. Practical recommendations by need

• Very cold apartments / poor heating: choose fleece/polar or thick brushed polyester onesie or a two‑layer approach (thermal base layer + flannel pajama). Retail Tex/Penti style items are best value. (Carrefour.ro)
• Normal heated home, want natural fibers: look for heavy cotton flannel from Romanian brands (Sofiaman, Ama). They balance warmth and breathability. (thetrends.ro)
• Cold sleepers who want style: wear a close‑fitting thermal base layer plus a cotton/flannel top; or choose high‑pile fleece for lounging. (Penti.com.ro)
• Gift / special occasion: silk (Megami) for luxury — pretty but not the warmest practical winter sleepwear. (businessmagazin.ro)

5. Sizing, care and durability pointers for warmth retention

• Look for “brushed”, “polar”, “fleece”, “flannel”, or “termal/thermal” on product pages — those are the warmest for winter. (Carrefour.ro)
• Wash care: heavy brushing and pile can compress if heated/dried aggressively — follow care labels to keep insulation loft. Product pages often list wash instructions. (e-homecollection.ro)

If you’d like, I can:

• Pull specific winter products (current models/prices) from Sofiaman, Ama, Megami, Tex/Carrefour, and Penti and compare their exact fabrics, GSM or pile descriptions, and prices — I’ll list the warmest picks and links. (I’ll need to fetch live product pages.)

Would you like me to find current in‑stock winter pajama models from these Romanian sellers and compare materials and prices?
